Investigators found huge, empty bottles made for prescription pills in Sage Stallone’s home, triggering a probe into potential drug-dealing, according to published reports yesterday.

Authorities want to link the bottles to doctors or pharmacies, in similar fashion to the probes of Michael Jackson’s and Whitney Houston’s deaths, the Los Angeles Times reported.

Celebrity-gossip Web site TMZ, citing anonymous law-enforcement sources, took it a step further, and reported that detectives are looking at a “likely scenario” that Sylvester Stallone’s son was dealing Vicodin.

Sage’s lawyer could not be reached for comment yesterday.

Investigators are eyeing his death as an accidental overdose. There will be no formal ruling until results of toxicology exams come back.

Cops don’t believe that 36-year-old Sage Stallone was a victim of foul play, and his heartbroken family still has questions.

“They don’t have suspicions, they just don’t know what to think,” said private investigator Scott Ross, working the case for his pal and Sage’s uncle, Frank Stallone.

“Frank said to me ‘We don’t have people pass away in our family from anything but old age. How does this work?’”
